Product Overview
A glow plug heats the combustion chamber before cold starting. When one or more plugs fail, the engine may crank longer when cold, start unevenly, produce white smoke for several seconds or depend heavily on warm ambient temperature to start.
Cross-reference research ties this plug to Bobcat 843 and Gehl 5620/SL5620/5625/SL5625 along with many Shibaura/Iseki-derived diesel applications. Published dimensions include M10 × 1.25 threads, roughly 85 mm overall length and a 10.5V rating, which are useful checks against the removed plug.

Frequently Asked Questions
Should all glow plugs be replaced together?
Not always, but plugs of the same age can wear similarly. Testing all cylinders helps decide whether a full set is appropriate.
What installation precaution matters most?
Use the engine manufacturer's torque specification; over-tightening can damage the plug or cylinder head threads.
Compatibility can vary by engine, serial number and equipment configuration. Match the original part number and physical configuration whenever possible before ordering.
